How many men became president of the US without having been elected?

There have been nine Presidents who did not win a presidential election before becoming President including four who won presidential elections after becoming President. The Vice Presidents who replaced the first four Presidents to die in office never won a presidential election. The Vice Presidents who replaced the other four Presidents who died in office won re-election at the ends of the terms in which they assumed office. Gerald Ford, however, was appointed to the vice presidency after Vice President Agnew resigned in 1973, and he ascended to the presidency when President Nixon resigned in 1974. He ran for re-election in 1976 but lost to Jimmy Carter, so he never won either a presidential election OR a vice-presidential election.
